The instructions also do not call the inode to the attention of the learner as the definitive way to demonstrate mastery of the hard link concept. Showing the number of hard links, as noted, is certainly a valid and important concept, but only demonstrates that there are hard links, and that they increment on each file when a new link is created, Demonstrating that they are the same file (espeically after-the-fact of its having been created) requires revelaing the inode and this should, in my opinion, be added here to both the shown command and the explanatory verbiage. I add it when leading learners through this exercise, but for learners without a live instructor, adding it would be beneficial.
@trialestes great callout!
